切片参数对MEX 3D打印PLA模型冲击性能的影响
Effect of slicing parameters on impact resistance of material extrusion 3D-printed PLA models
摘要
Abstract
This paper reports an investigation on the influence of three key slicing parameters,printing orientation,extru-sion temperature,and infill density,on the impact resistance of material extrusion(MEX)3D-printed polylactic acid(PLA)models.Using Charpy impact testing and an orthogonal experimental design,the process parameters were sys-tematically evaluated and optimized.The results indicated that printing orientation significantly affected impact resis-tance,with the highest strength observed for the xzy orientation,followed by xyz,and the lowest for the zyx orienta-tion.Furthermore,impact strength increased concomitantly with higher extrusion temperatures and greater infill density.Analysis of the parameter effects revealed that infill density exerted the greatest influence on impact resistance,followed by printing orientation,and then extrusion temperature.An optimized parameter set was identified:xzy printing orienta-tion,an extrusion temperature of 210 ℃,and 80％infill density.The models printed with these parameters achieved a peak impact strength of 6.89 kJ/m2,representing the best performance observed in this study.关键词
